Application filed October 29, 1913. Serial No. 798,061;

'Be it known that I, Josnr FoL'rznR, a subject of the Emperor of Germany, residing at Metz, Germany, haveinvented new and useful Improvements in Methods of Making Imitation Textile Products from Solutions of Cellulose or Plastic Substances; and I do hereby declare the following to be full, clear, andexact description of the.

invention, such as will enable others skilled in the art to which it appertains to make and use the same,-reference being" had to the accompanying drawings,""and to letters or figures ofreference marked thereon, whichform a part of this specification. This invention relates to a method of making imitation textile products from solutions of cellulose,- (nitro-cellulose, viscose, acetyl cellulose and the like)- or from plastic substances (casein, fibrin, and the like) or from rubber composition, said solutions or substances being applied .in a thin layer corresponding to the thickness of the "desired body by means of. a spreading apparatus to a base, a cylinder, a disk or an endless cloth-band. The substance applied arranged immediately behind or 'atacertain distance. from the laying on or spreading apparatus, which is directly connected.

to the pressing apparatus. The positively driven engraved roll presses against the 1 base and stamps out" of the viscous mass,

tion of the arrow 3.

bodies corresponding in their form to the engravings of said goifering roll. The method according to the presentinvention may be carried out, for instance, by means of the devices illustrated on the accompanying drawings, in which- Figure 1 shows a vertical longitudinal come solid. In order to prevent a lateral pressing out of the massthere are provided on the cyl nder 4 two lateral wings or blades 5 connecting the laying on apparatus. 1 to the pressure r0112. The product, which has become sufliciently solid, is now conveyed farther upon the circumference of the cylinder 4 and itv is then immersed into ahardening liquid contained in a tank 6, in which said cylinder 4 is .partly arranged. The

shaped product is then pulled off by the 1 cylinders 7 and it is finally fed by means 'of continually rotating rolls 14 to several suitable bathsll, 12 and 13 contained in tanks or receptacles 8,9 and 10, respectively for the purpose of being further treated (for instance, acidified, cleansed and the like); The finished product is then finally to said base'is crowded in front of an engraved pressure or goifering' roll, which is pressed out imitation products adhere very frequently to the engraved parts of the presvsure roll 2 from which they can then only I be detached with difficulty. -This is particfularly the case if thick embroidery imitations are used, and in order to prevent such an adhering of said products it is necessary to sprinkle the engravings of .the roll 2 with a suitable liquid for precipitating 'o'r hardening the mass, the excess of the liquid being carefully taken 0d the surface of the roll by means of stripping off knives 16. Also the circumference of the drum 4- has to be cleaned very carefully before it comes againnear the outlet of the laying on hopper 1 to take up a new layer of cellulose.

For this purpose there is provided a receptacle 17, which lies close against a part of the circumference'of the drum 4 and which is provided with a lateral" outlet opening 18.- This receptacle" 17 is also connected to a pipe; 19, which may convey into said receptaclea cleansingliquid which neutralizes the preceding precipitating bath. As indidated in the drawing, the lateral walls of ice the receptaclelf act at the sameltime as stripping ofl members, while a heated drum '20 arranged between the receptacle l7 and precipitated.

- the plastic substance, or the appearance and texture of the products are affected if such powder is sprinkled together with the precipitating fluid into the engravings of the pressure roll 2, so that these fibers adhere tothe surface of the products while the plastiemass is shaped and simultaneously In choosing the difierent dimensions of the engravings it has to be taken into consideration that the products shrivel considerably during the drying process, not-' withstanding the tension exerted upon them,

, and since said tension acts usually only inthe longitudinal and the transverse direction of the products the shriveling will be greater in the thickness of the latter which is reduced during the drying of said finished products,

',and instead of being an imitation of clothr the product will have moreof a paper or parchment like appearancei The engravings of the pressure roll have to be, therefore, at least 40-80% deeper and about 25-50% larger than the finished goods. The finished product, or its relief or raised parts, may be ornamented between two goifering or silk-finishing calenders held correspondingly apart,-whereby care has to be taken that the thickness of the fabric is not much reduced, but above'all that the products are not pressed flat. a

7 Instead of usinga mass consisting of a solution of cellulose there may be used a mass consisting of cellulose, for-instance cotton fibers or cellular tissue, which are not 1 completely dissolved bi l the solvent liquid,

but'only rendered solu c. There may also be-mixed with the said massstarch and gluten, dissolved for example in lye, as well as a shining, homogeneously or differently colored glass powder. These dough like substances produce softer and less vitreous products and the. small particles of glass L powder produce in the products special light effects. Instead of producing imitation metal-like bodiesby admixing metal powderwith the mass, said bodies may-be metal- 'lized by means of galvanizing rocesses and .by using electricity. Such pr note can also be metallized by mixing iron powder with the mass andthe finished product'may'he covered with copper by dipping it into asolution copper. The presence of iron causes the copper to precipitate the form of a thin layer on the fabric imitation, which eventually may be covered with lacquer. Cheap imitation textile goods have only to be covered with a metallic or glazed lacquer. It is also possible to make light, soft and porous products by preparing a mass consisting of two different solutions and of different primary products (for ex:

ample of a solution of cellulose and of fibrin) one of these primary products (for example the fibrin) being afterward removed from the finished product. There remains then a connected, microscopic skeleton, which can easily be colored and whic is of particularly soft texture.

' For the treatment of the substance in the hereinbefore described manner there A may be used, for example, the device shown in plate or an endless band. The speed of rotation of the pressure roll 2 can be-chosen quite independently from that of the cylinder 4; in other words, said roll may have a greater or smallervelocity than the cylin-' der. If there exists sucha difference in the speed of rotation between the parts 2 and 4 there is produced at the point where .these parts' 2, 3, 4 .touch each other, a certain. frip tion which results in better formed roducts. If the press roll2ldoe's not tone the cylinder 4 and if there iis'p'rovided between t ese two parts a small ace,'.then the pro duced product will not e perforated and the formed articles adhere to a. simultaneously of whlch corresponds to the distance between the pressure roll 2 and the cylinder 4. This arrangement produces intagliated products.

For the manufactureof products, which have to be perforated there may be provided one-the pressure roll 2 a stripping off or rotatory brush 22, which brushes off or removes the film parts eventually adhering to the unperforated roducts. Inthe arran ement shown'in ig. '2 the stamped out textile product is not-conveyed farther by the cylinder-tbut it remains inserted in the produced film-like base, the thickness engravings of the roll 2 till it conve ed tQ'af stripping off roll 23. The pro uct "passes over an endless band 25- passing over rolls 23 and 24 and'it afterward falls into a receptacle 26, where the. loose or wound u pnoductsaresucce'ssivel acted-upon b -dlfl'erentbaths and chemica productswhicl i 18o mayharden, subsequently treat, cleanse and eventually bleach "or" dye said: .product. This arrangement eliminates different manipulations, so that the goods are less torn or damaged. The cleansed roducts may be treated with magnesium ch orid,-glycerin or glycerin-like solutions. These textile products-have the drawback in that their thicker partsfeel much too hard as compared with ordinary cloth or embroidered fabric ieces. As; the engravings of the pressure rol have rto be about -80% deeper and in particular larger than the finished, dried product, it is possible to obtain, in an indirect manner, a much softer and a more plastic product if 7 thick threads are not produced by means 7 ribs 27 are formed in the products.
